The methodology distinguishes kitchen waste into two categories (expired or spoiled food and leftovers) and food waste generated by students into five types (first course, second course, dessert, bread, and inedible waste).<\/p>\n\n\n\n<p>At the same time, the <strong>causes of food waste<\/strong> were also identified. Initial results point to an average waste of close to <strong>14% per diner<\/strong>, with bread being the most frequently discarded food. In addition, approximately <strong>40% of plate waste is related to individual preferences and sensory aspects of the meals.<\/strong><\/p>\n\n\n\n<p>This first baseline measurement will make it possible to <strong>establish the initial situation of each school <\/strong>and will serve to assess the real impact of the future educational and gastronomic interventions to be carried out.<\/p>\n\n\n\n<p>The development of this methodology aims to ensure that the results of the GUSTOS project are useful not only for the participating schools, but also for other schools interested in implementing <strong>food waste prevention strategies<\/strong> in their school canteens.<\/p>\n\n\n\n<p>We invite you to learn more about the GUSTOS project here: \u00a0<a href=\"https:\/\/www.ausolan.com\/en\/gustos\/\">https:\/\/www.ausolan.com\/gustos\/<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The initial phase reveals an average food waste of 14% and lays the groundwork for future educational and gastronomic interventions.
